Sources: Twins try to keep Carl Pavano

The Minnesota Twins have stepped up their efforts with Carl Pavano and are making a "serious push'' to re-sign the free agent right-hander, two baseball sources at the winter meetings told ESPN.com.

Pavano, who posted a 17-11 record with a 3.75 ERA last season, has attracted interest from the Washington Nationals and Florida Marlins this winter.

But the signs continue to point toward him returning to Minnesota, where he revived his career after an unsuccessful four-year stint with the Yankees.

With Jorge De La Rosa, Jake Westbrook, Hiroki Kuroda and several other starters already off the market, Pavano is generally regarded as the second-best free-agent starter available after Cliff Lee.

Pavano, 34, has a 97-89 career record with a 4.34 ERA in 12 seasons with Montreal, Florida, the Yankees, Cleveland and Minnesota.
